Amen to this. I did quite a bit of digging last year to find a dumb TV that did the basics (high panel quality, input switching, HDMI-CEC) well and otherwise just stayed out of the way, and I gave up. A couple of companies have a 'commercial' line that gets close to this, but they were priced totally out of line with their consumer counterparts. Similarly, many TVs have a 'hotel mode' that comes close, but it's invariably undocumented and can easily lead to bricking your TV. It's a wasteland of a marketplace right now, and only getting worse.
