I have plotted the spectrogram for an audio in mp3 and wav file as shown in Figure 1 and 2 respectively.
Does it means that wav file has higher audible frequency range which is in brighter color while mp3 is in dark blue which has lower frequency?
Figure 1: mp3 spectrogram
Figure 1: mp3 spectrogram
wav spectrogram
Figure 2: wav spectrogram
Thank you.

It's difficult to say given that they are plotted with two different colorbar axes limits. Set them to be the same and you can verify it easier visually. Try
colorbar;
caxis([-200 0])
Do that for each plot.
