HR has limitations at the top end because of lag, and (to a lesser extent) on long sessions because of cardiac drift, but these can be compensated for with experience.
Yeah I think I definitely need to do a formal LTHR test, the zones on my monitor are clearly off. 220 - age is the default on my monitor, so it works out to 189 max for me (I'm 31). I regularly and easily see the upper 180s when doing intervals all the time, and I have even registered over 210 going all out trying to chase down a pack. So clearly 189 is not my max, and I think it's throwing off my zones, especially for steady state threshold efforts. They don't feel hard enough even though my HR is supposedly at 80% or whatever.
