I don't think HDMI 1.3 vs. 1.3a on the TV is important since you'll only be sending video and not audio to it. I understand that Deep Color is optional on 1.3 anyway, and I'm not aware of any relevant xvYCC source devices. Here's the wiki.

I have really enjoyed my JVC HD-ILA TV. I don't notice any SSE.

DBD, I'm sure you'll be delighted with the Panny, the JVC or the Sony.
