Sorry but your knowledge seems to be quite outdated. HDR on Linux has worked for a while now and Bluetooth is just as easy to use as it would be on a TV. Installing the entire OS takes less than an hour.
Not sure what you are on about regarding "configuring Linux PCs", you just install an OS once and forever not have to deal with insert proprietary TV OS bullshit, which is far more annoying and time-wasting than configuring something on a Linux PC. Not to mention the conveniences that you get with a real PC instead of some Android toy OS.
The "appliance" is more "convenient" right until you find something wrong/annoying/inconvenient about it and have to deal with the usual bullshit. I mean, sure, if all you need is watching Netlix it will be fine.
tl;dr your comment might have made sense ~5 years ago, but right now you have no clue what you're talking about and basically just repeating "linux pc hard and bad" propaganda
