Answer is simple Tata Play had changed LCN of all channels after NTO implementation thus giving it option to arrange channels as per slab agreement agreed upon in RIO deal signed with various broadcasters thus it moved certain channels in genre as mentioned/stated in RIO by concerned broadcasters while for other operators like Airtel Digital TV, Dish TV etc same is not the case thus it would not have been possible to accommodate / place certain channels in respective LCN slots in the specified genre as doing so while keeping current LCN placement orderof channels in various genres would violate slab agreement signed for with other broadcasters or there would have been option to place these channels in end LCN slots while also making required changes in LCN of other channels of these broadcasters to comply with slab selected in the RIO agreement while not violating slab order as signed with in RIO agreement with other broadcasters.....so for this reason these operators would have chosen option to continue having these few channels in genres where it were earlier placed till LCN Realignment is done to make required changes
They finally fixed the low audio issue of Viacom 18 hd channels (colors hd, MTV beats hd and Cineplex hd)
Also I notice some improvement of other channels audio like &pictures hd or maybe my mind playing tricks
