I do not know what the measurements are although I understand the difference. Whether the difference is significant will depend on how loud the units actually are when installed. If either of them make the equivalent noise in your room indicated by their numbers (63dB or 71dB), they are both totally unacceptable. My 2 listening rooms measure 15dB and 25dB, respectively, and I am rarely bothered by the noise level in the latter room (although I am frequently aware of it).
So, an 8dB difference might not be worth $750 if you are comparing 15dB with 23dB but, imho, it would be worth every penny if you are comparing 25dB with 33dB.
So, are those in-room measurements of installed units or something else?
