To put your question in perspective, currently Blu-raystats.com lists a total of 1,099 Blu-ray discs.
So far, no Dolby TrueHD 7.1 are listed, even though the codec supports 7.1.
There are 44 DTS-MA 7.1 discs listed.
When connected via HDMI the 44 DTS-MA 7.1 discs can be decoded in the player and sent as PCM to your Integra, or sent as bitstream from the player and decoded in your Integra. In either case, the the 7.1 signal would be downmixed to 5.1 after telling your Integra that you have a 5.1 configuration.
I can't speak for all Blu-ray players, but in my Panasonic DMP-BD55, it is not possible to set the speaker configuration in the player when connected via HDMI. This is not a problem since in your case this would simply be done in the Integra.
For analog audio connections the BD55 does have settings which permit downmixing to 5.1 and/or selecting the number of active speakers in the player. However, this is a connection you are not likely to use when connecting a Blu-ray player since the Integra has HDMI. I merely mention analog audio in the interest of completeness.
When decoded in your player to PCM, depending on how you setup your player, you may send either lossy or lossless audio to the Integra. This depends on whether you enable secondary audio in the player or not.
