Indeed, "no-transform" prohibits compression (as per the standard). It would be nice to find why the server emits it. You may try to get rid of it using an http-response replace-header rule but I would not recommend it, as you could figure much later why the server placed it and regret causing random trouble by compressing these (or maybe some objects really need it to be respected and others not).
