Has anyone actually been to a tint shop and/or measured how much UV is blocked by the privacy glass and glass roof? I am considering getting a light (3M Crystalline) tint, and the tint shop suggested that I get Crystalline 90 over the rear privacy glass as that is practically a clear film but would block UV, and said that privacy glass just darkens the window but generally doesn't block UV.

I don't want to spend money on getting clear tint aft of the B-pillar if this doesn't give me any noticeable benefits, so if anyone has actually measured UV and heat energy that's being rejected by the very dark rear privacy glass, I'd appreciate it if you can tell me your results. Seat of the pants impression is that the privacy glass does a pretty good job of rejecting heat, as it is quite a bit cooler in direct sunlight.
