Gas turbine market share data from 2020
Siemens（Germany） 29.7%
GE（US）27.6%
Mitsubishi（Japan）21.8%
Ansaldo（Italy）12.4%
A jet engine is a gas turbine and marketshare is not the same thing as capability.
Even though the photo is blurry, the left nozzle is obviously longer. I wonder if TVC has been installed.
p.s. Apparently the shorter nozzle is WS-15.

Are you (and users on Weibo) absolutely sure?
To admit, at this stage until not really clear images are available we cannot be sure ... however it is again the typical Salami-tactic by unveiling it bit by bit.

Original Weibo poster didn’t state it explicitly, but this is heavily implied. China wouldn’t need to test a WS-10 variant alongside another engine.
But the question is indeed valid, are these images maybe older ones showing a so far not known J-20 fitted with one WS-10 and one AL-31?
I know, the first time we saw a WS-10C on a J-20A was in September 2017 and it already had two fitted ...
... and indeed the WS-10C is shoerter than the AL-31FN:
The WS-15 should have fewer compressor stages so it should also be a shorter engine.
