IIRC if I do this on my Bravia I also lose the image enhancements.
You mean you turn off slopping up your image? The kind of person who wants a dumb TV probably wants any "enhancements" off too.
At least on our TCL (which has an array of thousands of back lights) some of the unhance options actually need to be turned on.

We bought it because it has crazy high brightness (it is in a bright room with direct sunlight hitting the panel while we are watching it), and while it can beat back the sun, it cannot do so by just turning all the zones on 100% because it would melt or something.

So, if all the image slopping were turned off, the contrast ratio would drop 100x, and the TV wouldn't really be fit for purpose.

(For when the sun is not actively trying to kill the panel, I have a de-slop shortcut setup. That also has the backlight enhance stuff turned on -- as low as possible -- to get true black on the LCD. It works OK. OLED is not quite there yet for this corner case.)

This kind of trade-off is often a dark pattern used when forced to offer a feature by regulators or by competitors offering it. The evil trick is complying with the regs or being able to advertise the feature but making it so unattractive users won't activate it, enabling the manufacturer to still earn that sweet $35-$60 / yr from advertising, app install payments, rev share and selling your viewing data.

> the image enhancements.

Having spent a couple decades working in and around digital video production tooling and engineering, as well as being a filmmaker and home theater enthusiast, it's worth mentioning that today almost all television image enhancement features are net negative, even if they make the image subjectively 'pop' or motion appear smoother on typical scenes, they'll introduce artifacts or trade-offs in other kinds of scenes.

In my experience doing a lot of testing over the years with objective signal analysis tools at work as well as subjectively across 7 generations of upgrades in my own home theater, the trade-offs aren't worth it. There are a few context and content specific exceptions but they're quite rare and usually involve slightly improving significantly degraded signals which no longer exist in most home theaters (eg noise reduction in analog sources like laserdisc, DCT macro-block smoothing in highly compressed old MPEG 1/2 sources or dynamic range expansion on legacy SD sources).

With today's 4K and HD digital sources encoded at high bit rates in modern codecs, the director, colorist and mastering engineer can finally deliver their precise intent all the way to your eyeballs. The ~$20 chip calculating synthetic frames and pixels in your TV introduces surface curb appeal at the cost of artifacts and a poorly integrated image. If it actually made the image look better, the director and colorist have more and better tools than that $20 chip that they're already applying to the source. You're just turning a $20 chip loose on 'full auto' to guess at (and often undo or muddy) intentional enhancements manually applied frame by frame over days by experts.

Do whatever you like but I encourage you to critically audition each of those enhancements across a range of source types (4K, HD, HDR, HDR10, SDR, 24, 30, and 60 frame) and diverse scenes (low-light, quick panning, smooth dollies, and synthetic test signals, etc). Once you compare the before/after across that breadth back-to-back you'll see what I mean. I run my calibrated, high-end 3-laser projector (150" screen) as close to neutral, native settings as I can get and it looks sensational. And to be clear I'm not being a purist, if 'enhancements' really improved some scenes meaningfully without degrading other scenes, I'd be "Fuck the director's intent, it's just better." But for every scene an enhancement improves, I can queue up a scene from another film it makes noticeably worse. Fortunately, on most high-end Sony TVs you can get an un-hyped, accurate image in the standard UX without going to the calibrator or factory menus.

Yep, generally you don't want anything the TV manufacturer markets as "enhancements." They basically all add things to the signal that were not part of the director's or video editor's vision. Any cinephile will remind you that there is one correct setting for "brightness," "contrast," "color," and "tint". "Sharpness" should almost always be zero, and any other setting that claims to "enhance" the picture should be turned off for correct output.

The worst ones now are the "motion smoothing" modes that take your normal FPS movie and try to interpolate them up to 60FPS, 120FPS or even 240FPS, giving them that cheap, crappy "soap opera" effect. Turn it off as soon as you turn on your TV for the first time.
