Liminal, Im pretty new here, as well.
Believe me I have been using hyperion NG now for 2 years now, out standing project! on with Raspi OS and Hyperbian Lite. no issues that I can't trouble shoot myself and learn from errors, and the vast info found online and here on this site, is outstanding, it sounds like you wanna take your time, reach out to others like your doing. you'll get answers.
like the admin/developers and senior users have stated above. 
RPi4 (hyperbian)
w/ Pengo 4k grabber downscale 1080p
3 x 2.4Ghz Wifi nodeMCU esp2288 (WLED)
(2) 662 LEDs(144/m ws2812 ) around 75' in Samsung crystal UHD
(1) 191(60/m) around media console.
hey guys, I noticed this as well, I found that if you turn off led output on/off in the dashboard of Hyperion, then the lights connect to the grabber to see the lights. this is the only thing I found with Alpha 10, that gives me a little of a problem when turning on.
