Aristo rail is more of a yellow-golden colour and tends to stay that way, ..............
The PIKO and LGB R1 points are slightly different, the straight bit is 320mm long on the PIKO but only 300mm on the LGB, otherwise the same. You can mix and match PIKO and LGB track to your heart's content, even the point motors are interchangeable. My indoor layout is about 50:50 LGB and PIKO. The LGB sleepers look more like narrow gauge sleepers, well worn and grooved, the PIKO ones more like standard gauge, but you hardly notice the difference unless you are looking for it.The short answer is "Yes", but |(and there is always a but) I understand that Piko points differ from LGB ones. Someone more knowledgeable than me will explain further.

The curved points (available from Piko and TL45) are for much larger radii...... BUT you can get a short curved point from Bertram Heyn that might just do the job:
