Well my signals have gotten a lot worse.
My modem lost the two upstream channels again despite now being on the 3.5 dB leg of the splitter and the one channel is now reporting 53 dB power.
In addition my downstream signals dropped by about 3 dB. They were positive and now they are negative.
My TV is actually worse. The SNR for channels now ranges from 29 to 32. To the TiVo's benefit, it's still working with these lousy signals. It is having to do a lot of error correction though.
Whatever Comcast did, it's not getting better.
Here's what my modem is reporting now:

I wish SmokePing was working as I'm very curious as to what that looks like.
