Here's the disappointing response that I received from WXLV when I mentioned I am receiving their digital signal:
I'm glad someone is watching our new digital signal. Sorry about the
test pattern, I'll explain.
The color bars are only for testing of our digital encoding equipment's
multi-channel capabilities and relative tests of off air reception. The
bars are actually encoded high definition at a low bit rate. We will
replace bars on 29-1 with standard definition programming and will only
have a single channel of standard def programming available for the near
future. At this time we are transmitting standard def programming on

I expressed my disappointment at the lack of hi-def.
