This contribution reports results for VTM 17.0 vs VTM 16.0 for both the HDR CTC (JVET-Z2011) and the high bit depth CTC (JVET-U2018). It is reported that these results show differences between BD-rate changes for the PSNR and wPSNR metrics. Further, it is reported that the results show that there are also different results in terms of these metrics on a per sequence basis, with some sequences performing much better than others. It is suggested that if HDR is considered an important future use case of VVC that it should be strongly encouraged that any proposal is backed with results for both HDR and SDR CTCs.
