Fake 24-bit FLAC?

So I have a 16-bit FLAC audio file of a song and also a 24-bit version. However, I don't know whether the 24-bit FLAC is legit since when opening in Spek, the spectrogram is different. I know the 16-bit is a legitimate FLAC file but unsure about the 24-bit one. I also don't know much about audio I will admit and I'm sure I can't tell audio differences between the 2 but since I had access to 24-bit, was curious.

16-bit:
Size: 32.4 MB
Bit Rate: 921 kbps

24-bit:
Size: 54.8 MB
Bit Rate:  1601 kbps


16-bit SPEK:


24-bit SPEK:

The 16 bit one clearly has noise shaped dithering filling out the high frequency range.

What's the source of the 24 bit song?

That looks like it's lossy mastered which is legit.

MQA is known to use filtering and hi-frequency noise, so it only confirms my assumption that it's legit regarding to encoding used.

Btw. it's actually lossy.
