I'm 99.9% sure that the so called studio range RGB is nothing but a mistake made by unprofessional engineers in the earlier days, because:
a) no television system transmits video in RGB space, so it makes no sense to preserve some "headroom" from the 8-bit range for some metadata that does not exist in the first place.
b) YUV<->RGB conversions are ALWAYS defined on full range RGB, this limited range RGB could not be properly displayed (without some non-standard scaling applied first), or properly converted to YUV by any standard. it's an abomination
