The lack of automatic color space switching makes it next to useless for me.
That's fair, and I don't doubt for a moment that it's accurate/correct for you and your use-case and situation.
For me? Owning a 2017 Sony means that the color space switching isn't an issue for me anymore, which is convenient. I still have a few complaints/wish-list items about Shield, but they're pretty small/pretty minor (for me), and Shield is a "about perfect" for my needs, certainly compared to all the other options out there (including AppleTV).
I'm not up-to-date on the recent goings-on of AppleTV, but if it still doesn't support:
1) The HDHomeRun View app for my live TV and whole-home-DVR that I'm running
2) bitstreaming of TrueHD and HD-MA for my MKV rips via Plex
3) Google Cast for ease of use/compatability with our mobile devices (or, conversely, if Apple allowed us to "airplay" from our Android devices to their player the way Google supports cast from iOS to Shield)
4) Steam portal for my son's growing enthusiasm and collection of games
... then it wouldn't be "about perfect," for me and anyone else that likes/prefers those features....
