Well I can imagine for their 30th anniversary of their UK broadcast on the 1st September, they're planning something big, because when I checked the 28.2E satellite data (specifically, 11307H), this recently pop-up for an encrypted service titled "Nickelodeon Dual", which is about to start testing: www.digitalbitrate.com 

I think in this case, "Nickelodeon Dual" means dual audio, as it carries the English audio track and the audio description/narration track. en.kingofsat.net 

In the past 10 years or so, kids channels tend to rebrand when most schools close for the Summer in England and Wales (with the exception to POP which did its last rebrand on 1st September 2020), either on the Friday or Monday, so I think the rebrand will happen somewhere around Friday 21st July or Monday 24th July.
