The Audacity waveform rendering is a bit misleading because each pixel is reflecting the peak of nearly 10,000 samples. Here's a higher-resolution look ("Open Image in New Tab" and click to zoom for detail) at one segment of the track:
From the waveform analysis, you can see that the LRA of the selected segment is fairly narrow at 2.1 LU, but the dynamic range is quite high at 38.59 dB. The effect is minimal variation in music intensity, but a substantial difference between the quietest and loudest sounds in that segment.
I'd guess that the degree to which this causes ear sparkles is probably not achievable when mastering to plastic.
