In this store. They are available in many countries, including the US, EU, Japan, etc. If you are from the UK you can buy ALAC version (Apple Lossless) for just £3.99, on the other hand, I do not know if it is more profitable to buy 24-bit/48.00 KHz from Qobuz for almost the same price (£4.49). You can always re-encode it to 16-bit lossless if you need and still keep the 24-bit version.
If it's about me - I have no option to buy the 24 - bit version. I can only get lossless from Juno.
At Juno there is also lossless clean version of it (available only for specified countries).
