Just don’t buy OLED and it won’t darken, if you buy OLED get ready to replace the extensive TV every 5 years no matter what brand you buy.
As for removing bloatware I have no idea since my TV is from around 2010 and I only use it connected to the computer, but you can always just get a raspberry pi and install kodi on it and use the TV as a normal dumb TV. It’s also good for your privacy.
This, but synthesiser, while also play piano sounds on my midi keyboard, I find that synth sound is the most etheric, specially if I dial it myself or edit the presets.
