Technically speaking, the definition of CRI is related ONLY to other light sources at that same color temperature.
If your light is 98 CRI at 3200K CCT, then it is near perfect in the scale of 3200K CCT light sources.
This does NOT mean that it renders colors better than another light source at a different CCT. It ONLY relates to the CRI for lights at that same CCT.
This is part of the definition of CRI. It is ONLY valid at the CCT that it is in.
Saying my 92CRI light at 2700K has better color rendering than your 90CRI light at 5000K is not an apples to apples comparison, and is really not valid.
