The issue here is the preemphasis of the signal (higher frequencies are amplified) employed in the emo_large.conf config file, so that the spectrum is not "white" anymore.
If you change line 81
https://github.com/audeering/opensmile/blob/341aea9ce52bc63d7fe75098027a394994f8493b/config/misc/emo_large.conf#L81C1-L81C24
to
reader.dmLevel=frames
you will get the expected result.
Generally, you might want to try also ComParE_2016.conf, which does not use preemphasis and has been updated more recently:
