Osram Cool Blue Intense 5500K vs. 6000K

Hi guys, has anyone had any experience with the new burners from Osram with 6000k? Is it worth changing from 5500k to 6000k? More bluish would be great! There was once the “Hyper blue 66140CHB” from Osram with the ultimate blue stitch, insert a picture. But how it looks, you can’t buy it anymore. Very bad … Or do you have an inside tip in terms of 6000k and bluish light? Best regards
