I'm not sure what pattern you are concerned about, but in general, no, you needn't worry. The errors you measured on the LTR-1610B are a little higher than what you might get with other media or another burner, but are still acceptable. Importantly, you aren't showing any C2 errors.
If you want to lower your error rate, try some other media like Taiyo Yuden, Ritek, or Verbatim DataLife Plus and see how they do.
As for the much lower errors shown on the 163D, don't trust them. Although KProbe will run with the Lite-On DVD-ROM drives, the measurements made these drives are artificially low and don't accurately reflect the quality of the disc.
I don't see anything here that should stop you from "still burning with (your) LTR-16101B."
