Can ADV7850 handle UHD 4K30?

The Datasheet states the device can handle up to 2160p 24Hz.  I assume the datasheet means 4096x2160. Can this device

also handle UHD 4K30 i.e. 3840x2160 at 25.00,  29.97 and 30.00 FpS ?  My concern is that the device was originally designed and optimized for cinema content (hence the  24Hz) and cannot support 30Hz. Nowhere in the datasheet, are the terms 4K or UHD mentioned.

According to application note AN-1277 on ADV7850 cyclic redundancy, the CRC check deals with up to 8,000,000 pixels, whereas 4K is more:  3,840 x 2,160 = 8,294,400 . That is to say, this could be an indication the device agrees to receive 297MHz at its TMDS inputs PHY-wise, but content-wise is incapable of internally handling the extra amount of data required by 4K30 (Or- the datasheet was written before 4K standards were released ?)
