Correct. Currently supported are WAV, MP3, AAC, OGG, Opus, WebM, ALAC and FLAC (and formats that are backwards compatible with one of these formats), unless DSD is supported by your browser natively (which is not the case as far as I am aware).
You may open a feature request for it, but chances are very slim that it will be implemented.
